Improvement in weighing-scoops



UNITED STATES PATENT. OFFIGEL MICHAEL L. MERY, OF CHICO, CALIFORNIA.

IMPROVEMENT IN WEIGHlNG-SCOOPS.

Specification forming part of Letters Patent No. 196,245, dated October 16, 1877 application filed August 24, 1877. E

To all whom it may concern:

Be it known that I, MICHAEL L. MERY, of the town of Chico, county of Butte, and State of California, have invented aIVeighingScoop and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings.

My invention relates to a novel combination scoop and weighing device; and it consists in constructing a scoop in combination with a spring-balance, located in the scoop-handle, with scale and pointers on the handle, and a stop so arranged as to save the spiral balance, spring from damage when the scoop is thrust into any hard unyielding material.

It also relates to certain anti-frictional devices and a balance adjustment, as will be more fully described by reference to the accompanying drawings, in which- Figrne 1 is a perspective view. Fig. 2 is a vertical section.

The scoop A has its movable stem B sliding in the handle 0, and outside the spring-case H, as shown. The guides or rollers D serve to keep the stem in position, so that the spring may work free; also to prevent friction while weighing. A similar set of anti-friction rollers, D, are fixed to the lower end of the stem, so as to work between the outer and inner case 0 and H.

A spring-stop, E, is so arranged on the han (lle as to be directly under the thumb when the handle is grasped, and a slight pressure of the thumb on it when the scoop is thrust in any material prevents the stem 13 from bein pressed back.

A spiral balance-spring, G, plays within a socket or case, H, which fits inside the stem 13, and is made fast to the inside lower end of the handle.

A thimble, I, placed in the lower end of socket H, holds the end of the spring G, and a nut and screw, J, in the end of handle 0, operate upon this thimble, and serve to adjust the tension of the sprin This screw J can be made hook-shaped, and can be used to hang the scoop by when not in use.

A scale, K, is fixed on the handle, and graduated on both sides of a double pointe L-one side to ounces, the other to quarte pounds or any other desired scale.

\Vhen the scoop is in use, the handle is na inallygrasped so that the thumb is direct over the stop E, and a slight pressure on when the scoop is thrust into any materi prevents the stem from being pushed do upon the spring and causing any damage toi The combination of handle and stem is man stiff and unyielding by reason of this sto1, thus facilitating the scooping up of any har unyielding material.

When the material to be weighed is raise up in the scoop, the stop is released, and th balance being free to act, the weight of the m. terial will show on the scale.

This arrangement of scoop and scale giv two useful articles in one, and is very servic able where a large amount of material has t be divided by weight into small quantities.

Having thus described my invention, wheat I claim as new, and desire to secure by Le ters Patent, is-

1. The scoop A, with its hollow stem B fi ted to slide between the outer and inner hai dle and case 0 H, and provided with the ant friction rollers D D, in combination with th spring G and scale K, substantially as herei described. I

2. The scoop A, with its stem B and hollow double handle and spring-case O H, in comb' nation with the thimble or socket 1 and screx J, for adjusting and regulating the spring substantially as herein described.

3. The scoop A, with its stem B moving 1] the handle G, and provided with the balanc spring and scale, in combination with th spring-stop E, to prevent the movement of th stem B, substantially as herein described. 1

In witness whereof I have hereunto set my hand and seal.

MICHAEL L. MERY.
